Top 8 Reasons That Cause Hose Fails

1. Site Damage – Site damage is mainly because the hoses are used in tough and aggressive conditions such as construction sites or Mining sites. The hydraulic hoses in these tough conditions are easily to be abused. They are also easily to be hit or busted on by other objects like steel or rocks. While there is something the operator can do to prevent. The most helpful thing to do to help prevent site damage, is regularly checking over the machines, making sure that all the machines are used in good condition. Also we can use some hose protective like metal or textile reinforcement sleeves that will help prolong the hydraulic hose life.

2. Wear & Tear – Hose wear & tear is not something that we can really prevent. It’s inevitable during the hose using, with use it the wear and tear will come. While similarly to the site damage, with a routine maintenance and regular checking of your hose and equipment, keep a look out for the hoses that might be rubbing incorrectly. It will reduce the possibility of the hose operating in adverse conditions, thereby delaying hose wear&tear. The routine maintenance and regular checking will also greatly reduce the probability of your machine having an accident.

3. Fluid compatibility – The compatibility between the fluid medium in the hose and the inner wall of the hose will directly lead to the leakage of the hose or the contamination of the fluid system. Incompatible fluid media can corrode the hose, deform or separate from the wire layer, causing the hose to swell. Therefore, when selecting and using a hose, verify in advance that the fluid is compatible with the hose inner, fittings, and even the outer cover.

4. Bend Radius exceeded & kinks manifesting by fittings – Bend radius is one of the most important properties of a hose. When we choose and use the hose, we must refer to the bending radius parameter of the hose. When the hose is used beyond its own bending radius, the structure of the hose will be damaged and the toughness will be greatly reduced. At the same time, when the bending performance of the hose is exceeded, the fluid space in the hose will be compressed, which will also reduce the service life of the hose.

5. Heat Aged – When used for hot fluid transportation, the service life of the hose will be lower than that of normal temperature fluids. When the fluid passing through the hose is too hot, it will destroy the material and structure of the hose, and the service life will be shortened, or even directly ruptured. Therefore, when using, it is necessary to avoid overheating of the machine and cause overheating of the fluid. If this situation cannot be avoided, it is important to check the machine on time to avoid malfunction.

6. Improper installation – When you're looking for someone to hose your machine, make sure the person you're looking for is professional and discreet. Improper installation is one of the main reasons for hose problems. Be sure to carefully clean and flush these hoses or assemblies prior to installation to prevent fluid contamination. In addition, proper length of hose and proper force must be used to install. The fittings are snapped correctly, snapped in place, and the end of the hose needs to be adjusted into place. Any improper operation may result in leakage of the hose or even serious damage to the machine.

7. Improper Planning & Routing – Improper planning and routing can also cause hoses to fail. Improper routing can cause the hose to rub against itself or with other parts of the machine. At the same time, an unsuitable route will also cause the fluid pressure in the pipe to increase and the flow rate to become stronger, which will reduce the service life of the hose. Therefore, when installing, first select the appropriate length, the appropriate installation location, and the appropriate line to ensure that the hose will not rub against other objects.

8. Improper Hose Length/width – Improper hose length and size can quickly cause hydraulic hose failure. A hose that is too short will not have enough room for the hose to handle the normal expansion and contraction during use, which may damage the hose structure and reduce hose life. Therefore, before using the hose, be sure to choose the correct size and cut the appropriate length.
